The Claim
Markers of muscle damage—including creatine kinase levels, range of motion, muscle soreness, and arm circumference—do not differ significantly between young women and postmenopausal women following eccentric exercise.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After performing eccentric exercise, young women and postmenopausal women show the same levels of muscle damage as measured by creatine kinase, soreness, range of motion, and arm circumference.
See the scientific wording
Markers of muscle damage (creatine kinase, range of motion, soreness, arm circumference) do not differ significantly between young and postmenopausal women after eccentric exercise, indicating that age and menopausal status do not alter the acute physical damage response to this type of muscle stress.
When muscles are stretched under load, the outer membrane of muscle fibers stays intact in both young and older women, so fewer harmful substances leak out and the inside of the cells maintains normal calcium levels, leading to the same amount of swelling, soreness, and enzyme release regardless of age.
What the research says
1 studyThe study found that older and younger women had the same levels of muscle soreness, swelling, and blood markers after intense exercise, meaning aging doesn’t make muscles more damaged by this kind of workout.
